Collaborative team proves leaf width and biomass correlation in cowpea
In a collaboration between RIPE researchers and cowpea breeders from Ahmadu Bello University and the International Institute of Tropical Agriculture, the width of cowpea leaves was found to correlate with above-ground biomass across diverse germpla.....»»
Discovery uncovers a new leaf for redwoods
Redwoods are among the most well-studied trees on the planet, and yet their mysteries continue to surprise and delight scientists and nature lovers......»»
From museum to laptop: A visual leaf library is a new tool for identifying plants
Fossil plants reveal the evolution of green life on Earth, but the most abundant samples that are found—fossil leaves—are also the most challenging to identify. A large, open-access visual leaf library developed by a Penn State-led team provides.....»»
This gene regulates positive and negative immune responses in plants
The mechanism of plant defense mediated by the non-expressor of pathogenesis-related (NPR) genes in monocots (plants having a single embryonic leaf) is not well-documented. Now, scientists from Tokyo University of Science have discovered how the NPR.....»»
Detecting plant leaf disease using deep learning on a mobile device
The visual and tactile examination of plant leaves is a standard method for identifying disease in crops and horticultural products. However, such an approach can be highly subjective and is dependent on the skills of the examiners. Writing in the In.....»»
Less powerful black hole blows environment clean after all
An international team of astronomers led by Dutch scientists has discovered that even a weak jet stream from a low-active black hole can be a kind of leaf blower to clean parts of a galaxy. The observed black hole removes about 75% of the cold gas in.....»»
Leaf oysters: The unsung heroes of estuaries are disappearing
Camouflaged by a layer of silty mud, most people probably wouldn't notice the large flat oysters lurking beneath shallow water in Australia's coastal estuaries. These are remarkable "leaf oysters," and they can form reefs, produce mauve pearls, and r.....»»
Unexpected benefits from food competitors
A research team at the Max Planck Institute for Chemical Ecology has found that gravid tobacco hawkmoths (Manduca sexta) show an unusual preference for Datura plants that are already infested with leaf beetles when laying their eggs. The beetles and.....»»
Researchers built a gecko-bot to study how geckos glide and crash land
The findings could help improve robotic locomotion, making bio-inspired robots more robust Enlarge / A gecko perches on a leaf. A September study found that geckos are very good gliders, and their tails help stabilize them when they cr.....»»
New inoculation method can protect soybeans against devastating leaf blight
Reported in three major soybean-producing countries in South America (Argentina, Brazil, and Paraguay), Cercospora leaf blight (CLB) is a global threat to soybean. CLB causes dark-purple lesions on leaves and premature defoliation, which can diminish.....»»
Arriving in mainland Malaysia, banana Blood disease now poised to spread throughout Southeast Asia
The world's most consumed fruit and an important staple for many developing companies, bananas are increasingly threated by Blood disease, so named because cut banana stems look like they are bleeding. Blood disease causes fruit rot, leaf wilt, and p.....»»
Scientists solve the grass leaf conundrum
Grass is cut regularly by our mowers and grazed on by cows and sheep, yet continues to grow back. The secret to its remarkable regenerative powers lies in part in the shape of its leaves, but how that shape arises has been a topic of longstanding de.....»»
A beetle chemical defense gland offers clues about how complex organs evolve
Rove beetles are among the chemists of the insect world, concocting noxious compounds within their bodies that are weaponized to ward off predators, enabling the beetles to survive in leaf litter and soil in ecosystems across the planet. On December.....»»
New succulent species of Euphorbia discovered in Kenya
During a field investigation in open deciduous woodlands covered by lava outcrops in Makueni County, southern Kenya, in September 2018, a shrubby Euphorbia with densely stellate hairs on the abaxial leaf surface attracted the attention of a research.....»»
Researchers call for standards for biological imaging
Stained molecules in the cell nucleus, the inner life of a synaptic cleft, or the surface of a floral leaf: Modern microscopes enable researchers to examine processes that are otherwise invisible and located in tiniest structures of organisms. Howeve.....»»
Cell wall remodeling enables fungal network development in grasses
Scientists now have a deeper understanding of how a fungus develops a symbiotic lifestyle inside grass leaf and why the grass leaf fails to defend itself against the intruder, thanks to research coming from Massey University in New Zealand and the Un.....»»
Bacteria and plants fight alike
A brown blotch on a plant leaf may be a sign that the plant's defenses are hard at work: When a plant is infected by a virus, fungus or bacterium, its immune response keeps the disease from spreading by killing the infected cell, as well as a few sur.....»»
First moth species on Alpenrose discovered
An Austrian-Swiss research team was able to find a previously unknown glacial relic in the Alps, the Alpine rose leaf-miner moth. It is the first known species to have its caterpillars specializing on the rust-red alpine rose, a very poisonous, widel.....»»
Staying green: Genes responsible for leaf browning after pesticide treatment identified
Sorghum, an underrated ancient grain, is slowly becoming well known as a superfood due to its nutrient-dense and gluten-free nature. Sorghum syrup is widely used as a healthy alternative to molasses in the food industry, and this cereal is also used.....»»
Keep your garden tidy with a backpack leaf blower
